I first thought about it, but it conflicts with outputs of
non-readable objects (i.e., #<smob xxx> etc.).
I think my second format is better because you can safely
close a block by ')'. ##(title title) is okay, but
#<title title> is an error because the reader considers
`title>' to be a single symbol.
By the way, is it a good idea to rewrite Guile's web pages
using this notation? I generate my personal pages like this:
(define title "My page")
(define menu
'(("Links"
("GNU" "http://www.gnu.org/";)
("Guile" "http://www.gnu.org/software/guile/";))))
(define (menu->html menu)
...)
(define main-page
(string-append
##(h1 title)
##(p "Hello")
))
(define page
##(html ##(head ##(title title))
##(body ##(table ##(tr ##(td (menu->html menu))
##(td main-page))))))
(display page)
